lMPROVEMENT IN SUKER-ROD .DRAWERS FOR DEIEF WELLS.

The Schedule referred to ln these Letters Patent and making part of thesame. l

bottom of a'long pumping-rod, reaching nearly or quite tothe bottom ofthe well, commonly five hundred to eight hundred feet. This longpumping-rod is made up of a series of rods, each fifteen to twenty feetlong, called sucker-rods,4 screwed together endwise.

. Sucker-rods commonly are of wood, v ironed oi, as

A thirnble-socket (a Ashort iron tube, with the oriice a plain hole atone end, and a tubular screw at the other,) is fastened to each end ofeach rod, the plain hole over the wood, by rivets laterally through theiron and wood;` a screw-pin, a short iron bar round at the ends, and -ascrew on each end adapted to the tubular screws onthe socket-thimbles,with a short square or angular body between the screws, for convenienceof holding and 'griping, isthen screwed into a thirnble of eachrod,thus, when tinished, leaving each rod with a screw-thirnhle or4mortise at one end and a screw-tenori at theother;l

and, practically, the rods are joined by screwing the the foot of oneonto the head of another.

Putting in sucker-rods to a well has been done heretofore commonly, asfollows: l

-To a chain or rope 4from a windlass attach a short iron bar, having asocket at the other end, in which is aitubular screw, to fit over thescrew-pin 'of a sucker-rod; screw the socket of this bar onto the headci' -a sucker-rod, and letit into the well till the ;quare or angular'part of the screw-pin is down to the top of' the well; unscrew the ironv4bar, screw it onto another' rod, screw the other end of the other rodonto the upper end of the one in the well, and let both into the well-till the screw-pin of the last is 'down to the top of the well, and soon; and l drawing sucker-rods is the same process, partly reversed.

This, invention is a modification and improvement of my improvedtube-drawer, which is the subject oi' la separate application for apatent, and its 0bject is to hold a sucker-rod, suspended by a gripearound the angular vpart of the screw-pin, instead of by a thimblescrewed onto the end; and..

lhernatnre ofthe invention is to adapt the socket of my improvedtube-drawerto fit onto and gripe the angular body of' the -screw-pin ofa sucker-rod.

llhe following description and accompanying drawing, having like'letters of' reference, fully illustrate the invention.

A is a socket or main body lof a clamp to go over and hold a sucker-rod.

f B is a bail, pivoted to the socket A and adapted to swing over andhold downthe screw-pin of a sucker-rod, when in placewithin thesocket.

C is a swivel attached to the top of the bail B.

l) is a part, showing one end of' a sucker-rod.

E is a socket-thimble, adapted to go over the end of a sucker-rod, D,and with a tubular screw in the end ofthe thimble part.

F is a screw-pin,- with .a screw 'on each end, adapted to fit into theend of a socket-thimblm'E.

a is a slot or mortise vertically through the socket A, and laterallyopen through at one side, and through nearly to the side opposite, largeenough to go over easily and gripe closely the angular part of thescrew-pin F. l) is a recess or rabbet over and around the slot a in thesocket A, from thetop vertically, part wayy through, adapted to iit andreceive and make a seat' for the shoulder of a screw-pin, F.

c is theangular main body of the screw-piu, F, large enough in diameterbetween any two of its dat sides to fill and easily go in the slot a ofthe sock.- et A.

(l. is a shoulderl ou the screw-pin F, between the angular body c andthe screw at each end, projecting radially out beyond the screw and anyflat side.

c is a screw on each end of each screw-pin F, and

on the inside of the thirnble end of eac-l1 socketthimble E. y fisafproject-iou on the back side' 0I' the socket A, vopposite to theopening of the slot a, for convenience of holding a socket over a well,and for the bail B to rest on when swung down.

'g is a long shank or handle tothe bail B, if deg sired.

To work the invention, put the slot a. of the socket A over and onto theangular body c of the screw-pin head F of a sucker-rod,-D; lift up thesocket till a shoulder', d, of the sucker-rod, strikes and rests on theseat or rabbet l); swing the bail B over the head of the sucker-rod;attach arope or chain from a windlass to the swivel C, and let down ordraw up, as desired.

'The merit of the invention is theineans of holding and handlingsucker-rods, when suspended, by griping around them, instead of screwinga socket into their heads. 1t is a much safer and handler way, and savesmuch time; and the essential feature oi' the invention is in adaptingthe socket-aperture oi' my improved tube-drawer to lit a shoulder andtwo fiat sides of a sucker-rod head, as hereiubefore described.

I claim- A-sucker-rod drawer, in which a slot and recess of a holding-socket are adapted to receive and hold a combined sucker-rod,substantially as described.
